Two-dimensional guard structure and a radiation detector with the same |
摘要 |
A semiconductor device comprises a piece of semiconductor material. On a surface of said piece of semiconductor material, a number of electrodes exist and are configured to assume different electric potentials. A guard structure comprises a two-dimensional array of conductive patches, at least some of which are left to assume an electric potential under the influence of electric potentials existing at said electrodes. |

1. A guard structure for a semiconductor device, comprising: a two-dimensional array of conductive patches on a surface of said semiconductor device, comprising a contiguous area of conductive patches located at or near an edge of said surface, at least some of which are left to assume an electric potential under the influence of electric potentials existing at sides of said two-dimensional array for controllably lowering absolute value of electric potential on said surface, and one or more guard rings that encircle a central portion of said surface, wherein at least one of said guard rings is interrupted by a sequence of said conductive patches. |
